Dunn, 34, and a passenger in his 2007 Porsche died after the car left the roadway and burst into flames, West Goshen Township police said. The crash occurred near the Philadelphia suburb of West Chester.

Born in Ohio, Dunn grew up in New York, before moving to West Chester, Pennsylvania, where he would hook up with his future ‘Jackass’ sidekick Bam Margera on his first day of high school.

He appeared on MTV shows “Jackass” and “Viva La Bam” and the three “Jackass” big-screen adaptations. He also was the star of his own MTV show, “Homewrecker,” and hosted “Proving Ground” on the G4 cable network.

Dunn recently celebrated his birthday on June 11. Hours before his death, he posted a photo of himself and two friends with drinks on Twitter.
